IMPBQVED DITGHIN G MACHINE.

TO ALL WHOM IT MAY'CONG-EItN:

Be it known that I", NATHAN STARBUCK, of Wilmington, in the county of Clinton, and State of Ohio, have invented a new and useful improvement in a Ditching Machine and I do hereby declare that the following is a full, clear, and exact description thereof, which will enahle those skilled in the art to make and use the same, reference hcing had to the accompanying drawings, forming part of this specification, in which- Figure 1- is a vertical longitudinal section taken in' the line :v 2', fig, 2

Figure 2 is a vertical transverse section of my improvedditehing machine, taken in the line 3 y, fig. 1.

Figure 3 is a cross-section, taken in the line n u, fig. 2, showing the sliding-yoke connection,

Figure 4 is a front end view of the carriage-frame.

Similar letters of reference indicate corresponding parts.

This invention relates to several new and useful improvements in a ditching machine, for which Letters Patent were issued to me on the 1st day of August, 1865, which consist in placing a pair of guiding-wheels under the front end of the frame, hanging the cutting-wheel in an adjustable sliding-gate or yoke, changing the form and position of the dirt-scraper on the cutting-wheel, and attaching a fender to throw the dirt from the scraper to the sides of the ditch.

A is arcctangular frame. mountedon two-wheels B B inthc rear, and a pair of guide-wheels C C hung on a holster, M, placed under the front end of the frame. D is a-smaller frame within the frame A, upon which is erected a gallo\rs-.fr=nne, E, placed transversely. A vertical sliding-yoke, F, is hung in the frame E, to which is suspended the cutting-wheel G, which wheel is similar in all respects to that described in my aforesaid patent. On one side of the frame Eare placed chains or a, runningJrom the upper to.thc lower part of the side-pieces, which chains a a serve as hearers for the ends of a pair of hoisting-hooks, b b,- that are attached to the end of a lever, 1i, suspended by ahoek and eye, 0, to the top bar of the yoke F, and also by a chain, d, to the top of the frame E, as shown in fig. 1, for the purpose of raising and lowering the yoke F, and thus graduating the cuttingwhccl G to cut deeper or shallower, as required. Thc'hooks b b are shifted in the chains a a to raise or lower the yoke. In my patent aforesaid a straight or flat seraper was placed against the front part of the cutting wheel: but in my present improved arrangement I place the scraper I in the rear of the cutting-whcelG, and curve the upper part like thc mould-beard of a plough, to throw the dirt upon one side, The scraper I is fastened to a pendant, g, that is hinged upon a part of -the yoke F in such manner that the scraper shall point downwards upon the face L i the cutting-wheel G, and scrape away any adhering earth as it revolves. Below the scraper I, on both sides of the cutting-wheel G, and running lengthwiseof the-frame A, is placed a horizontal. sheet-metal fender, K, havingslrelving sides which throw and deposit any dirt falling frenrthc scraper outside of the ditch which is. cut.

Theopcration of the machine is the same as that described in my Letters Patent aforesaid.

Having thus described my improvements, I claim as new, and desire to secure by Letters Patent- The eomhin'ation of the vertically adjustable yoke I, cutting-wheel (i, lever H, scraper I, suspended in the rear of said wheel-G to the hinged pendant y and fender K, arranged and operating as and for the purpose herein set forth.

NATHAN STARBUCK.
